Is it important for the overheads to be the same model mics in the Glyn Johns drum method? Isn't spacing and placement more important in this method than using 2 of the same mics?

I have 3 LDC mics, one each of: SP C1, Rode NTK, Kel HM-7U - I was hoping to try them all out to see which one sounds best in which position. My first inclination is to put the C1 as the side mic by the floor tom pointing over to the hi-hat, since that mic is probably the one that has the most expended high end for the hat as well as surprisingly full bottom for the toms. And then try the Kel or the NTK over the drummer's shoulder looking down at the snare and kick pedal.
57, e906 or e914 on snare top, Blue kickball on kick - and i think I'll try a mono Joly modded RSM-4 (ribbon) for a room/ front of kit mic...

mostly concerned about whether or not it'll be OK to use different LDCs for the overheads.
